How to install Bumblebee on Arch Linux

In this article I will describe how to install Bumblebee on Arch Linux. The Bumblebee-Wiki provides the following description for the software: “Bumblebee is an effort to make Nvidia Optimus enabled laptops work in GNU/Linux systems. Such feature involves two graphics cards with two different power consumption profiles plugged in a layered way sharing a single framebuffer”. Please be extremely cautious throughout the whole installation procedure, depending on your system you may end up with a messed up driver or system configuration! This “How To” is based on my system, here are the most relevant specs:

  • Lenovo ThinkPad T420s
  • CPU: Intel Core i7 – 2620M with integrated GPU
  • Graphics: NVIDIA 4200M Optimus Graphics (NVIDIA GF119M)

How to install and configure NetworkManager and network-manager-applet on Arch Linux with Gnome3

In this article I will describe how to make networkmanager and the network-manager-applet (aka nm-applet) work on Arch Linux with GNOME3. Of course there are other networking-tools available, however I prefer the use of networkmanager and network-manager-applet, because they integrate them selves very well into GNOME3.

Please notice that some parts of this how to were taken from Arch-Wiki-Networkmanager and Arch-Wiki-Beginners-Guide and I highly recommend reading those two articles.
